This issue started for me a day ago out of the blue. This on a PC on Xbox.
Everytime the sim starts its as if its a new install and I need to set up preferences again which do not seem to be saving. Once its up and running its great but this does add another 5 minutes each time I start the sim,not the end of the world, I know.
I tried deleting the UserCfg.opt file but to no avail. I am currently downloading a fresh install which may be some time as my speed is 33Mbits/s, its been downloading for 12 hours and Im currently only at 68%.
I’ll let you know if this sorts the issue.
